Soldiers inspect the wreckage of the airliner that crashed minutes before landing.

The flight data recorder has been located, NBC’s Fakhar Rehman reported from Islamabad, and the so-called "black box" was expected to reveal why the plane went down. But the apparent cause was that pilots were flying low under heavy clouds and hit high-tension wires as they approached Benazir Bhutto International Airport, he said.
